The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
A quote from Captain Charles Moore says, “Only we humans make waste that nature can’t digest.” This is completely true. Causes of ocean pollution vary, but the most commonly known are sewage, chemical run-off, land run-off, oil spills, ocean mining, and littering. Pollution can enter directly into the ocean by sewage ways. This is often how harmful substances from mining sites come to be in the ocean. Chemicals from industries and agricultural sites can run-off into the ocean.
Trash, Trash, Everywhere! Text By: Ashley Atkinson Edited By: Hannah Hunter and Jesse Lewis The life of your plastic water bottle can go way further than just the trash can. Our ocean is so polluted by our actions and carelessness that even us humans are being affected, sea animals, and surrounding animals are all being greatly influenced by the polluted waters. Our ocean is extremely polluted with plastics and other trash that humans have put in there. Specifically, 80% of the pollution that’s in the ocean, is because of us.
There are many harmful chemicals in the oceans of the world. For example, there is a chemical called mercury in the ocean. According to, “Google” mercury is, “the chemical element of atomic number 80, a heavy, silvery-white metal that is liquid at ordinary temperatures.” Mercury can lead to many issues the contribute to ocean pollution. This chemical can enter the ocean in a great deal of ways. For example, there was an enormous amount of mercury being dumped in the ocean in the past when people were not aware about the impact the mercury would have to the marine life (Oceanus Magazine).
The oil spill took a huge tool on alaskas fishing industry, forcing many Alaskan citizens which depended on the fish for their income to be pressured into some kind of a depression. In particular, the oil spill had affected trade of Alaska, particularly the industry of fishing in the region. According to surverys taken fishermen of Alaska have lost over three quarters of a billion. This is due to the oil spill because it ruined the Alaskan salmon in the region. The total damage done to the ecosystem and fish lost weighed in around six hundred million dollars (Fernando,
Global Warming Affecting Coral Reefs are worth $375 billion each year. They earn this money by attracting tourists. People also make a profit from the fish species that live in the coral (Casper 182), so if all the coral die due to global warming, humans will be affected as well. Coral are marine plants, and marine environments are the most diverse habitats in the world. If the planet was to lose all the coral in the world, it would decrease the diversity of the ocean (Casper 184).
While researching about how pollution affects sea turtles, we faced some issues on finding different types of pollution. As most people know, the plastic waste that is being dumped into the oceans and onto the beaches is becoming a main food source for sea turtles. When sea turtles see this trash, they consume the plastic causing death or severe sickness which has caused this species to become endangered. They also get tangled with the plastic in the ocean restricting them from normal movement and function. During our research, we found that there are more types of pollution affecting sea turtles than just plastic waste in the ocean.
Bleaching occurs when corals are exposed to water containing toxins, which cause coral reefs to lose their color and also leave them susceptible to death and disease (Pierre-Louis). One of the main culprits? Sunscreen. Thousands of tons of sunscreen wash off human bodies and into the ocean every year, and with “90% of snorkeling and diving
(Editing) The popularity the three cruise ships increased because of that, the marine environment is also affected. It can carry 4,000 passengers and crew. The garbage dumping and the untreated sewage at sea, plus the release of other shipping-related pollutants Dredging creates many major problems for reef. The drastic effects are caused by suspension of silt.The strongest effects are caused by suspension of silt, sedimentation, turbidity, oxygen reduction and the release of bacteria and toxic matter. A massive quantity of either coarse or fine particles will bury the corals, which are unable to withstand cover for more than one or two
Recent concerns that jellyfish populations are increasing have stimulated speculation about possible causes including climate change, eutrophication, over fishing and invasions (Jennifer E, 2007). The moon jellyfish has become a bit of a nuisance to many different fishing companies, they diminish the size of commercially important fish larvae by either direct predation or due to the result of food competition (Dawson and Jacobs 2001). Reports of human problems with jellyfish have increased and have captured public attention. Jellyfish and jelly-like sea creatures come in an immensely diverse range of forms. If a jellyfish is cut in two, the pieces of the jellyfish can regenerate and create two new organisms.
Beaches, docks, and other shallow, oxygen-rich areas provide a suitable habitat for the clams. Because of this, Asian clams greatly impact swimming areas since their sharp shells can cause injuries among swimmers. Also located in shallow areas of lakes, typically, are water intake systems, which Asian clams also have the tendency to clog and ultimately destroy. Since the town of Lake George 's main drinking water source is the lake, this creates a huge issue. The clams also clog water intake systems in private boats and homes, costing owners hundreds of dollars to fix.
This research is helpful because it will allow business owners and tourists know when a red tide will occur and when to stay away from waterways. Unfortunately, there is not much that can be done about the marine life until they are actually affected by it. The United States is working on creating a building to focus on the prediction of red tides: Its goal is to improve existing models to explain more accurately and then predict the complex progression of a red-tide bloom. Successful forecasts could, for instance, allow fishermen to scoop up shellfish before a bloom takes hold, warn businesses to brace for a drop in beach tourism or alert managers to which environmentally sensitive areas they should be monitoring most closely (Schrope 24). This 1.25 million dollar center for red tide prediction will hopefully be able to target a red tide bloom before it actually occurs, but for now the most that can be done is to monitor where the bloom will move based on wind and water currents.
This statistic just shows how diverse and enigmatic the ocean is. Despite the ocean’s abundance of marine life and complex ecosystem, it is being destroyed by fisheries. How are these fisheries destroying the ecosystem of the ocean? The answer is overfishing. Overfishing is the depletion of fish stock by too much fishing.
This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth. Most sharks only have one or two pups every time they give birth. These factors make the time-period
